Among adults with ADHD, one of the most common problems in daily life is procrastination. ADHD is characterized by attention as well as suboptimal decision-making deficits, indicating difficulty in making long-term reward choices. However, little is known about the relationship between suboptimal decision-making or temporal discounting (TD) and procrastination among adults with ADHD. This study aimed to investigate whether ADHD symptoms enhance the relationship between TD and procrastination. Fifty-eight university participants completed questionnaires about procrastination and an experimental task which measured TD rates in reward and punishment conditions. Only the reward condition showed that ADHD symptoms significantly strengthened the association between the TD rate and procrastination. This study revealed that even when ADHD symptoms were high, higher TD rates were associated with more procrastination, while lower TD rates were associated with less procrastination. The results suggest that procrastination interventions for adult ADHD-prone individuals need to pay attention to reward responses.
在患有注意力缺陷多动障碍（ADHD）的成年人中，日常生活中最常见的问题之一就是拖延。ADHD的特点是注意力不集中以及决策能力欠佳，这表明在做出长期奖励选择时存在困难。然而，对于患有ADHD的成年人来说，欠佳的决策能力或时间贴现（TD）与拖延之间的关系却鲜为人知。本研究旨在调查ADHD症状是否会增强TD与拖延之间的关系。58名大学参与者完成了关于拖延的问卷调查以及一项在奖励和惩罚条件下测量TD率的实验任务。只有奖励条件显示，ADHD症状显著加强了TD率与拖延之间的关联。这项研究表明，即使ADHD症状严重，较高的TD率也与更多的拖延相关，而较低的TD率则与较少的拖延相关。结果表明，针对易患ADHD的成年人的拖延干预措施需要关注奖励反应。
